A
simulation and experimental study of the histogram generated from the
normalized diffusion signal measured along multiple gradient directions is
presented. Voxels exhibiting an FA of
at least 0.8 are identified as representative of single fiber voxels, and
used to derive diffusion signals for multiple fiber crossings, in the range
0-90deg. The results illustrate how the histogram changes systematically with
crossing fibers within a voxel, and suggests that the histogram can be used
as a marker of the number of fibers within a voxel, and their relative
orientation.
